' WELT FOR BOOTS AND SHOES.

Specification of Letters Patent. v

Patented July 5,1910.

To all'abhom it may concern:

Be it known that I, Gnoncn F. Dunn, a

citizen of the United States, and aresideiit of Brockton, in the countyof Plymouth and State of Massachusetts have invented an for Boots andShoes, ofwhich the following description, in 'con nection with theaccompanying drawings, is

a specification, like numerals on the drawings representing like parts.

This invention relates to welts for boots and shoes as an article ofmanufacture.

In order that the principle of my invention may be readily understood, Ihave disclosed one illustrative embodiment thereof in the accompanyingdrawing, wherein Figure 1. is a vertlcal cross sectional view of a bootor shoe having my welt applied thereto; Fig. 2 is a plan view of a' weltembodying my invention; Fig. 3 is an edge view 0 tion on an enlargedscale of said welt; and Fig. 5 is a similar view showing the sameapplied to a shoe.

Welts have, previous to my invention been made of indeterminate lengthand sol as articles of manufacture for use in McKay and Goodyear bootsand shoes. Such Welts.

have in certain instances been proyided upon their inner edges withprojections or teeth, as shown for example in the patents to Wm. B.Arnold, No. 646,592, and No. 674,831.

While welts constructed inaccordance with said patents have been foundefiicient for the purpose intended, my present invention seeks to imrove the same in some respects, but is ca a le of embodiment in weltsgenerally, w ether or not they be provided with teeth or projections andwhether or not such teeth or projections be of the character disclosedin said patents. Preferably, however, the welt in which my invention isembodied is rovided with projections or teeth not only or the pur ose ofsaving stock, as

will be further described, but because of the peculiar coiiperation ofsaid teeth or proections with other features of the invention.

Welts constructed in accordance with the patents referred to as well asother weltssaid welt; Fig. 4 is a vertical sec-.

the insole it has been customary to provide a guide for said stitches inthe form of a channel or groove into which the sewing threads aresunk,'so that they will not be encountered by the stitching-threads thatsecure the outsole to the welt.

In accordance with my invention, I provide a piping strip of leather andstitch said pipin strip to the welt by a line of stitchin threa sadjacent the inner ed es of sai piping strip and welt and there orepassing through the teeth or projections upon the inner edge of the weltif, as preferred, the

latter be provided. Whether or not the channel in the lower face of thewelt be provided and whether or not the inner edge of the welt beprovided with teeth or pro- ,jections, the i ing strip and thewelt,'having previous y een stitched together as described, are securedto the insole by a line of sewin threads positioned between said line ofstltching threads and the outer edge of the welt and pipin strip. Inthis manner, the sewing threa s, which are customa rily chain stitching,are reinforced by the stitching threads, and in the event that thesewing threads break in the manufacture of the shoe or in its use ormore especially if they break in the repairing thereof, the de-' scribedline of stitching threads securing the pi ing strip to the welt willcontinue to ho d the piping strip and welt together.

Referrin more particularly to the drawing, the we t, who is of suitablematerial, is indicated at 1 in the several figures, it being preferablymade of indeterminate length as an article of manufacture. sired, theunder face ofsaid welt may be provided with a channel groove 2 toreceive the sewing threads, but it is unnecessary because thethreads'which secure the outsole If deto the welt are positionedentirely outside the piping strip and cannot therefore interfere withthe line ofsewing threads securing said welt to the insole. In otherwords the piping strip-acts as a spacin means between the line of sewingthrea s for the insole and the line of sewing threads for the welt isprovided with teeth or pro ections 3, such as shown in my co-pendingappllcation Serial No. 47 6,650. It will therefore be understood thatthe toothed edge of the welt is of reduced thickness and that a verymate outsole. Preferably the inner edge of the edge of the welt.

rial saving is effected in cutting the welts from a strip by theformation ofteeth as disclosed in said application.

While the saving of stock is important in the formation of welts and forthat reason it is important to sever the welt strips from each other byteeth 'as described, it is of very great importance that the inner edgeof the welt be of reduced thickness whether th1s reduced thickness beeffected by the formation of teeth or otherwise, because having formedthe inner edge of the welt of reduced thickness, I may secure the inneredge of the piping stri thereto and yet the combined thickness 0 theinner edges of the Welt and the piping strip will not be too great toprevent both being fed as a un1t through the usual welt guide ormanipulated as a unit. It has heretofore been suggested that a fillingstrip and a welt may be cemented or otherwise attached prior to themanufacture of shoes. but so far as I am aware. this has never been donein practice, for prior to my invention when a piping strip has beensecured to a shoe the piping strip and the welt have been fed throughseparate guides to the shoe. This necessitates a cumbersome and awkwardmode of procedure and has never met with favor. In fact, the objectionshave been so serious as substantially to preclude the use of pipingstrips with welts. In accordance with my nvention, however, the thinedged welt and previously secured piping strip may be fed as a un1tthrough a sin 1e welt guide and may be secured to the s cc as readily aswelts devoid of piping strips have heretofore been secured.

The piping strip is indicated at 4 in the several figures and iscomposed of leather and preferably of the best quality. The said .pipingstrip is folded uponitself and incloses at its outer ed e a suitablethread 5, which preferably is o braided cotton. The inner edges of thepiping strip are cemented together. It is important that the pipingstrip should snugly embrace the thread 5 at all points. This cannot beeffected by the use of cement alone, as the cement cannot extend intoclose proximity to the thread 5, and moreover there is a tendency of thefaces of the piping strip to separate from each other ad acent suchthread. I secure -a rmanently rounded bead like effect by a ine ofstitching Gextending through both portions of the piping strip as closeas practicable to the thread 5.

The welt and piping strip are secured together by a line of stitchinthreads 7 extending the entire length 0 the welt, said stitching threadspassin through the thin It wi 1. be apparent that were the inner edge ofthe welt of the full thickness of the body thereof, this line ofstitching would so increase the combined tion. In other words, it is notnecessary to alter the machines in order topermit the use of my improvedcombined welt and piping strlp.

The combined piping strip and welt pre pared and secured together asdescribed are secured to the insole 8 which is provided with the usualstitch receiving and retaining channel 9 and shoulder 10, the latterreceiving the edge of the upper 11 in the usual manner. The combinedwelt and piping strip having been applied thereto in the mannerindicated in Fig. 1, the several parts are secured by a line of throughand through sewing threads as indicated most clearly at 12 in Fig. 5.The said sewing threads are customarily of chain stitching. These sewingthreads sometimes break in the sewing operation, but much more often inthe use of the shoe and articularly in re airing the same. After theshoe is finishe the'welt is held in position by the said line of sewingthreads which secure it to the insole and also by the threads securingthe welt to the outsole. If the said line of sewing threads 12 shouldbreak at one or more points, the welt would still remain held becausesecured to the outsole, but the. piping strip would be released from thewelt at one or more points, were it not for the provision of the line ofstitching threads 7 ,which secure said piping strip to the welt.Therefore saidline of stitching threads not only serves to secure thepiping strip to the welt, but also to reinforce the action of the lineof sewing threads 12. The line of stitching threads 7 being positionedbetween the line of sewing threads 12 and the inner edge of the welt notonly are far less subject to reakage than the line'of sewing threads,but being ositioned as stated they do not interfere with the applicationof the sewing threads 12 when securing the welt to the insole.

It will be apparent that when my combined pipin str1 and welt is usedthe line of sewing a s securing the welt to the outsole is necessarilypositioned outside the outer edge-of the piping strip, and hence is sofar removed from the line of the'sewing threads 12 securing the welt tothe insole that'tliere is no danger of interference of said two lines ofthreads, and hence there is no need of providing the channel 2 toreceive and position said line of sewing threads 12.

Inasmuch, however, as many workmen are accustomed to use welts having achannel strip be secured thereto, thecombined p: strip and welt presenta sufficiently fiexi descriptive sense and not for purposes Correct'ionin Letters Patent No. 963,694.

and prefer to operatetherewith, I may and preferably do provide suchchannel.

It is a parent that by providing the welt with test or projections, orotherwise fashioning' it with a thin ed e, the welt is reng dered moreflexible at said ed e in its own plane. Therefore even thong the piping1ng einner edge to permit themto be bent as a unit about the toe of theshoe and properly a plied and secured thereto. In other words, thecombined inner edges of the welt and piping stri are substantially asflexible and as easy 0 application to the shoe as the unthinned edge ofthe usual-welt. Moreover, the piping strip conceals the teeth orprojections and infect is secured thereto and serves to position thesame. Therefore, the welt may be fed through its guide without anypossibility of the entangling of said teeth in the guide or any otherparts of the mechanism.

-The piping strip is secured to the grain face of the welt and not onlyenhances the appearance of the shoe but renders the same substantiallwater tight because the piping strip is we ged as it were, inbetween thewelt and the upper in such manner as to prevent access of water at thatpoint.
